How to force AI to do certain things

Like attack the other civ after certain number of turns. I read few months ago someone's post about it but I don't remember who was it and where to look for it now.

So, can I do it? or force AI to raze a city instead occupy?

If such a tread already exist about how to push AI to do tings please remind me and attach a link.
